Abstract

La présente invention concerne la fourniture d'un profil de souscription par défaut permettant de commander un dispositif terminal mobile dans un réseau de communication mobile de données par paquets. Une demande de profil de souscription de ce dispositif terminal mobile est envoyée de la passerelle. Un profil de souscription par défaut stocké dans un élément de réseau du réseau de communication mobile est envoyé à la passerelle. Cette invention permet d'éviter la nécessité d'émettre des profils de souscription du dispositif terminal mobile d'un réseau domestique du dispositif terminal mobile au réseau visité. Ainsi le signalement en temps réel et son retard associé sont abaissés. Par ailleurs, le profil de souscription est accessible même quand il y a des problèmes de connexion entre le réseau domestique et le réseau visité.
